Alpinestars Bionic Protection offers a … for the back.

1621-2 according to EU standards (standards since 2004) Level 2, more severe than those meeting the conditions of the first level, the dorsal Alpinestars Bionic is the result of innovations and development of the Moto GP.
Allowing a good dispersion forces (technology DFD) on impact, the dorsal Alpinestars Bionic does not mean imposing. Indeed, with a thickness and a weight content (announced 15mm thinner and 130g lighter than previous models), the dorsal, provided with 5 parts ergonomic adapting to the natural curve of the back, no problem should find its place under a jacket or a combination.

For good support on the rider, the brand has equipped its transalpine Bionic thermoformed by a wide belt on the sides and two adjustable straps.

Finally, for comfort in daily, air ducts are placed on the Bionic forming airflow to fight against perspiration.
